WebThe focal chord is a line segment that connects the focus of the parabola to the vertex of the parabola. The length of the focal chord is equal to the distance between the focus and … WebAnswer: Consider the parabola: The distance between the vertex and the focus, measured along the axis of symmetry, is the "focal length". The "latus rectum" is the chord of the parabola which is parallel to the directrix and passes through the focus. In fact the “latus rectum” used to be calle...
The chord of the parabola which passes through the focus is called the focal chord. Any chord to y2 = 4ax which passes through the focus is called a focal chord of the parabola y2= 4ax. Let y2= 4ax be the equation of a parabola and (at2, 2at) a point P on it. Suppose the coordinates of the other extremity Q of the … See more The combined equation of straight line y = mx + c and parabola y2= 4ax gives us the co-ordinates of point(s) of their intersection. The … See more Equation of the chord of the parabola y2 = 4ax whose middle point is (x1, y1) is (y-y1) = 2a/y1(x-x1) This can be written as T = S1, where T = yy1 – 2a(x+x1) and S1 = y12 – 4ax1. See more Consider the parabola y2= 4ax. If (x1, y1) is a given point and y12– 4ax1= 0, then the point lies on the parabola. But when y12– 4ax1≠ 0, we draw the ordinate PM meeting the curve in L.
